A field experiment was conducted at Eastern Block Farm, Department of Agronomy, Tamil Nadu Agricultural University, Coimbatore during kharif 2017 and 2018 (July to November) to identify the rooting pattern and productivity of maize under high density planting. The field experiment was laid out in randomized block design and replicated thrice. This study comprised of nine treatments which include four mixtures of spacings with one or two seedlings per hill and diverse fertilizer doses. The result of this study shows positive impact on root parameters like length, volume and dry weight. Higher root length was observed with crop geometry of 60 cm × 25 cm sown at two seedlings hill-1 with application of 200 % RDF, root volume was noticed under plant spacing of 60 cm × 25 cm maintained at one seedling hill-1 with 100 % RDF and wider spacing of 60 cm × 40 cm with two seedlings hill-1 with 150 % RDF registered higher dry weight of roots during both the years of study. With respect to yield, higher grain and stover yield was produced under closer spacing (30 cm × 25 cm) with one seedling hill-1 with application 200 % RDF.
